Dear All,
in my index I can see disturbing page breaks.

Is it possible to somehow define conditional keep-with-next rules?
I'd like to express:
(1) keep always the primary with the first secondary (this seems to be
implemented)
(2) keep always the first secondary with the next secondary
(3) keep always the last secondary with the previous secondary
And similarly for tertiary.
Deep down we have (spac-ver) this:
\definevspacing[preference][penalty:-500] % goodbreak
\definevspacing[samepage] [penalty:10000] % nobreak
\definevspacing[max] [category:1]
\definevspacing[force] [category:2]
\definevspacing[disable] [category:5]
\definevspacing[nowhite] [category:6]
\definevspacing[back] [category:7]
% together [category:8]
\definevspacing[overlay] [category:9]
\definevspacing[always] [category:0]
\definevspacing[weak] [order:0]
\definevspacing[strong] [order:100]
so we can have weights and so. However, in practice the problem is that
when combining different mechanisms their spacing settings might not be
tuned to each other. I will extend this mechanism when we have a bit
more control over some of the lists involved.
It's no big deal to set up something for an index, but it needs thinking
about how to deal with worst case scenarios and these will happen for
sure and you don't want to end up with a sequence of entries two pages
height running of a page, certainly not in a fully automated workflow.
It is on the to-be-loked-into-list, but as all things, it has to fit
into my agenda (read: to be done in what's left of my free time). I also
have to make sure then it does not mess up existing files.
For the moment playing with the before/after keys is the way to go.
